  Log:
  Fix two A-list corruption cases.
  
  When a meta-element indicates the next layer is all-allocated or all-free,
  the next layer is allowed to contain garbage.  The allocator must skip an
  all-allocated layer.
  
  Similarly when a free recurses through an all-allocated layer the next layer
  must be initialized so we can recurse down into it.
